"if you think childlike, you'll stay young. If you keep your energy going, and do everything with a little flair, you're gunna stay young. But most people do things without energy, and they atrophy their mind as well as their body. you have to think young, you have to laugh a lot, and you have to have good feelings for everyone in the world, because if you don't, it's going to come inside, your own poison, and it's over" Jerry Lewis

Note on Citations

The numerical citations refer to page number. The source's text-space (including footnote region) is divided into four equal portions, a, b, c, d. If the citation is found in one such section, then for example it would be cited p.15c. If the cited text lies at a boundary, then it would be for example p.16cd. If it spans from one section to another, it is rendered either for example p.15a.d or p.15a-d. If it goes from a 'd' section and/or arrives at an 'a' section, the letters are omitted: p.15-16.

The first definition for the proposition involves truth and falsehood. It is a complete state of affairs that is either true or false.

The Stoic proposition is an item of meaning (σημαινόμενον, semainomenon), i.e. a complete sayable (λεκτόν, lekton). A variety of ideas are involved in its definitions as reported by Diogenes Laertius:

A proposition is that which is true or false, or a complete state of affairs (πραγμα αυτοτελές, pragma autoteles) which, so far as itself is concerned, can be asserted, as Chrysippus says in his Dialectical definitions: A proposition is that which, so far as itself is concerned, can be denied or affirmed, e.g. 'It is day', 'Dion is walking'.

Diog. Laert. VII, 65, tr. Long/Sedley 1987: 206 part)

(109-110)

A proposition then is also a self-sufficient (complete) state of affairs. And it is something that can be asserted. This means that

the proposition is restricted to a certain time and a certain place as emerges from the following:

Someone who says 'It is day' seems to propose that it is day. If, then, it is day, the proposition advanced comes out true, but if not, it comes out false.

(Diog. Laert. VII, 65 = SVF 2.193, tr. Long/Sedley 1987: 203)

The proposition can thus change truth value in accordance with the changed circumstances (Long/Sedley 1987: 206)

(110bc)

The 'intransitive' sentence type dominates the discussion of simple propositions, in which referentiality plays a prominent part. Indeed, the questions of truth value and referentiality are the central concerns of the Stoic proposition as reported by our sources. (110-111)
